An expansion joint strip seal for use in roadways, bridges, buildings and the like to seal across a gap defined by a pair of parallel, elongated edge or frame members, which have generally C-shaped cavities opening towards the gap for purposes of supporting opposite lengthwise extending edges of the strip seal. The strip seal is formed of a suitable resiliently deformable material and defined by a web portion sized to span the gap and a pair of mounting bead portions joined to opposite edges of the web portion and adapted for insertion within the cavities of the edge members. Each mounting bead portion includes a solid or non-apertured main mounting portion, which is joined to the web portion and provided with a height essentially corresponding to the height of the cavity and a width less than the width of the cavity; and a tongue portion cantilever supported by the main mounting portion to project in a direction away from the web portion. The tongue portion is resiliently deformed, as an incident to insertion of the mounting bead portion into its cavity for purposes of establishing a bias or lever action on the main mounting portion tending to prevent subsequent disassembly of the seal.
